Hello!
You can only add variables with the same base and exponent
8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9
Put the sums together
12u^3 + 8u^2 - 6u + 9
The answer is

Hope this helps!
Answer:
I would be y
Step-by-step explanation:
sorry if it is wrong
Step-by-step explanation:
The area, A, in square yards, of a rectangular garden, is given by the function.

We know that, the area of the rectangle is given by :

Where l is length and b is breadth

Length = 2x
Breadth = (15-x)
For zeoes,

Length = 15 yards
Breadth = (15-15) = 0 yards
Hence, this is the required solution.
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
